Foswiki System Requirements

Low client and server base requirements are core features that keep Foswiki widely deployable, particularly across a range of browser platforms and versions. Many extensions exist which enhance and expand Foswiki's capabilities; they may have additional requirements.

Server Requirements

Foswiki is written in Perl 5, which is supported on Microsoft Windows as well as Unix and Unix-like systems (including Linux and OSX), on which it uses a number of shell commands and RCS (Revision Control System), a GNU Free Software package. It should be able to run on any server platform that meets the following requirements.

5.7 or higher (including GNU diff) Optional. Foswiki includes a pure Perl implementation of RCS (RcsLite) that can be used instead, at the cost of performance

GNU diff

GNU diff 2.7 or higher is required when not using the all-Perl RcsLite. Install within the PATH if not included with RCS (check version with diff -v) Must be the version used by RCS, to avoid problems with binary attachments - RCS may have hard-coded path to diff

Perl Modules

A complete list of the required and optional Perl modules can be found in lib/DEPENDENCIES.

The following CPAN modules are not shipped with Foswiki. Note that Foswiki extensions may add additional requirements.
Modules marked as Required may still be optional if certain default core features are not used.

Most of them will probably already be available in your installation. You can check version numbers with the configure script, or if you're still trying to get to that point, check from the command line like this:

perl -e 'use FileHandle; print $FileHandle::VERSION."\n"'

For more detailed dependency information, try the script dependencies_installer.pl located in the tools directory, which makes perl module installation easier. Run it with option -h to understand basics. This script requires confirmation before it actually does something.
